Dane techniczne

The NITECORE UMS2 dual-slot smart USB charger is designed for fast, safe and efficient battery charging. The UMS2 will reach a maximum total output of 4000mA when using a 2A USB power adapter. When the charger is powered or connected to a Quick Charge (QC) adapter, the screen will display "Quick Charge" and the single slot will reach a maximum output of 3000mA.

The brightly lit LCD display indicates battery status, charging time, charging current, battery voltage and type, cut-off voltage and charging mode. The UMS2 offers a power saving function that activates and dims the LCD display after 10 minutes if there is no activity on the buttons or battery.

The UMS2 supports various battery types (li-ion/imr/lifep04/ni-cd/ni-mh) and popular battery sizes.
